Introduction
If your BuddyBoss App gets stuck on the launch screen or fails to log in, your server may be blocking the V2 Authentication API. The app calls an endpoint like
https://www.[your_domain]/wp-json/wp/v2/users/[user_id]
If this returns a 400 Bad Request error, most likely your hosting environment is restricting access. Follow the steps below and share the details with your hosting provider to restore functionality.

Troubleshooting and FAQs
Q: I still get a 400 error after the host made changes—what next?
A: Request that your host check server logs (e.g., Nginx/Apache error logs or WAF logs) for clues about blocked requests.
Q: Is this related to BuddyBoss or WordPress?
A: It’s a server configuration issue affecting the WordPress REST API. BuddyBoss relies on that API for authentication.
